Question

A car traveling initially at 7ms-1 accelerates at the rate of 8.0ms-2 for an interval of 2.0s. What is it's velocity at the end of the 2s?

Answer 1

Explanation:

hope this helps. use the equations of motion for this

Answer 2

Answer:

u=7m/s

a= 8m/s^2

t= 2s

v=u+at

v=7+ 8×2

v=7+16

v=23m/s
